It's easy to "fire" a business that rips you off. Just go to a different one. It's a lot easier to patronize another business than to get government to fix the problem. But bad businesses and the politicians they own, I mean influence, often don't want you to have that choice.

No organization can do anything efficiently, or even reasonably, unless workers can be fired. Government workers' special protections are a reason taxes are high, bridges fall down, public schools decay, the CDC loses Ebola samples and so on.
